Archive tied to the ASUS Maximus VII Ranger motherboard, packed as a 327 KB RAR. The name gives no revision and does not say whether the contents are a boardview, a schematic or firmware, though ASUS boardviews for this series are usually .fz files of similar size. Extract it and check what is inside before use. If it is a layout, open it in FlexBV or another FZ-compatible viewer, and in every case confirm the PCB revision printed on the board matches the file.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
